Overview
The Dada DAM3-1600 Molded Case Circuit Breaker boasts an impressive rated current capacity of up to 1600A. These advanced electrical devices are perfectly engineered for safeguarding power distribution circuits operating with an alternating current of 50-60Hz and a rated current up to 1000A. Additionally, they're ideal for providing infrequent motor startups, preventing overloads, and offering robust protection against short circuits and undervoltage conditions.
Compared to our DAM1 series, the DAM3 series represents a leap forward in design, featuring a more compact size and higher breaking capacity, all while delivering superior energy efficiency.

Introduction
The DAM3-1600 Molded Case Circuit Breaker is engineered to automatically interrupt the current flow when it surpasses the set threshold. Its 'molded case' designation refers to the robust plastic insulator that forms the frame of the device, providing essential insulation between the conductor and the metal grounding components.
Working Principle
The operation of the DAM3-1600 Molded Case Circuit Breaker involves manual or electrical actuation to close the main contact. Once closed, the free release mechanism securely locks the main contact in position. The device integrates an overcurrent trip coil and a thermal trip element in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply, ensuring precise and reliable performance.
